The present invention at least includes following beneficial effect:
1, plastic cement injection nozzle in equipment is excessive; then actual internal area is big; the compressive load per unit area of plastics progressive die is low; formed and penetrate the situation that power is little; non-Newtonian plastics often can not make viscosity degradation cause mold filling difficulty because there is no big shear heat; the plastic cement injection equipment of the present invention for different volumes, thickness, material, shape plastics needed for the optimal injection amount situation different from the required power of penetrating; being provided with hand line nozzle more changing device below barrel, the setting of hand line nozzle more changing device makes the selection of the nozzle of different bore more flexible.Wherein, change the polarity of electric magnet, electric magnet can adsorb under electromagnetic action on the first permanent magnet opposite polarity with it, thus it is fixed on original nozzle one end, reduce the injection bore of nozzle, need to regain electric magnet, when recovering the injection bore of original nozzle, change the polarity of electric magnet, the setting of the second permanent magnet makes electric magnet opposite polarity with it can be sucked back on the second permanent magnet, simple and fast, thus realize selecting the most flexibly the purpose of heavy caliber and more small-bore nozzle in the case of not removing original nozzle.The setting of a pair pulley, the more changing device of the hand line nozzle on mainboard is enable to make mainboard level on a pair pulley slide, under the effect of block, mainboard does not falls out yet, so that mainboard form drawer type can the structure of pull, mainboard is made to pull out from barrel or be accommodated in below barrel as required, save space to be also convenient for using, more attractive in appearance.Hand line nozzle more changing device can better meet the needs of different plastic cement products, suitable injection amount decreases plastic cement products and the possibility of overlap flash occurs, reduces defect rate, thus obtains higher-quality product, time saving and energy saving and reduce cost, convenient and swift.
2, in the present invention, in feed hopper, the plastic rubber material entering entrapped moisture therein can be played the effect of a preliminarily dried by the setting of drying device, reduce plastic cement products filamentary silver stricture of vagina and the probability of bubble generation, simultaneously because feed hopper is infundibulate also ensures that plastic rubber material can't be lingered wherein, the serviceability of plastic rubber material can't be affected.The effect once filtered the plastic rubber material entered is played in the setting of screen tray, existing plastic rubber material raw material is often mixed with impurity and reworked material, wherein, reworked material low in glossiness, particle surface is dull, size is uneven, often containing impurity, physical and mechanical properties is the poorest and virgin material, if entering barrel together with virgin material, not only affect the performance of plastic cement products, it is also possible to work in-process thermal stress-cracking occurs or produces needle-like silvery white filamentary silver stricture of vagina as frost on plastic surface along stream direction, reduce production efficiency, the most dismountable screen tray can screen out the break flour in raw material, reduce the consumption of reworked material, ensure the quality of products material, dismountable structure is convenient takes off replacing at any time.First feed pipe is between screen tray and screen cloth, and screen the plastic rubber material gone out from the first feed pipe and enter barrel, the i.e. particle diameter plastic rubber material entrance barrel between screen tray Mesh Diameter and the Mesh Diameter of screen cloth, particle size range is less, size is uniform, decreases plastic cement products and produces the probability of filamentary silver stricture of vagina.The setting of stirring paddle not only makes plastic rubber material mix, contribute to particle diameter plastic rubber material between screen tray Mesh Diameter and the Mesh Diameter of screen cloth and enter barrel, and certain effect that raw material is dried can be played, reduce further plastic cement products filamentary silver stricture of vagina and the probability of bubble generation, be conducive to obtaining higher-quality product.
null3、In the present invention, the heater strip of M shape has bigger temperature radiation scope，Three pairs of equidistant front portions being distributed within barrel of heater、Middle part and rear portion，Ensure evenly the material in barrel be heated in whole barrel，The heating-up temperature of every part is monitored in multiple temperature sensors at any time，When temperature exceedes the upper limit，Single-chip microcomputer makes controller control switch cut out，Stop heating，When temperature is less than the upper limit，Single-chip microcomputer makes controller control switch open，Restart heating，Same temperature ranges stated preset by each heater，Ensure that the temperature in whole barrel is maintained at identical temperature range，Evenly plastic rubber material can be made to add heat fusing，And will not be because of the performance affecting plastic cement products too high or too low for temperature，Decrease and make because temperature is too high product that overlap or the too low probability making product embrittlement or lapping defect occur of temperature occur.
4, the glass fiber material of dopen Nano Graphene has good heat conductivility, the heating making heater strip has bigger temperature radiation scope, cover and make heating the most further evenly in barrel, do not have local temperature too high or too low, adulterate in convexity layer the higher nano-graphene of mass fraction, both made, near the top layer of heater, there is the function preferably making even heat radiate, circular protrusions in convexity layer can play certain self-cleaning effect simultaneously, it is difficult to be infected with plastic rubber material or other impurity, Nano-meter SiO_22The thermal insulation layer spraying of composite ceramic material, near the surface of barrel outer wall, plays good heat insulation effect, makes heat to scatter and disappear to outside easily.
Part is embodied by the further advantage of the present invention, target and feature by description below, and part is also by by being understood by the person skilled in the art the research of the present invention and practice.
